Abstrakt: Globally, large quantity of animal byproducts is generated from the slaughter of food animals, but there is lack of research articles related to drying of these byproducts and its use as pet food. Therefore, this study was conducted with the aim of utilization of intact whole buffalo liver by drying for pet treat, evaluating its shelf life and palatability. The intact liver surface was superficially sliced, and the surface was pierced. Thereafter, the livers were pretreated in 3% sugar and 4% salt solution (1 : 3 w / v) for 3 h followed by microwaving for 4 min and hot air drying at 60°C for 40 h (designated as T2L). The livers which were dried the same as T2L except surface piercing were referred as T1L, whereas the livers dried only using hot air oven were referred as control (CL). The moisture and protein contents of the dried CL and T2L were found to be 28.46% and 14.29% and 43.85% and 52.76%, respectively. Sodium dodecyl sulphate–polyacrylamide gel electrophoresis (SDS-PAGE) image of T2L revealed the presence of few low as well as high molecular weight protein bands which were absent in CL and T1L indicating a comparatively lower level of protein degradation in T2L. The shelf life of T1L and T2L samples based on microbiological and lipid oxidation analyses was found to be more than 60 days at 25 and 4°C. Palatability studies using dogs showed that all dried samples were highly palatable. Thus, it could be concluded that intact buffalo liver could be dried using surface slicing, with/without piercing followed by salt and sugar pretreatment, 4 min microwaving, and hot air drying at 60°C for 40 h. Future study should focus on the sensory properties such as aroma, texture, and flavor and sensory analysis of the dried liver by human. [ABSTRACT FROM AUTHOR]
